Do you mean that if UAL goes south Thai could cancel my tickets? </font>
Exactly. The money for the tickets does not change hands until
after you fly, so Thai would be flying you for free if UA wasn't flying still. They might honor the tickets as a goodwill gesture, but there is no requirement they fly you for free.
